GENERAL WARNINGS
CALIFORNIA PROPOSITION 65
Engine exhaust and some of its constituents,
and some dust created by power sanding,
sawing, grinding, drilling and other construction
activities contains chemicals known to the Sate
of California to cause cancer, birth defects and
other reproductive harm. Some examples of
these chemicals are:
Lead from lead-based paints.
Crystalline silica from bricks.
Arsenic and chromium from chemically treated
lumbar.
Your risk from these exposures caries, depend-
ing on how often you do this type of work. To
reduce your exposure to these chemicals:
ALWAYS work in a well ventilated area, and
work with improved safety equipment, such
as dust masks that are specifically designed to
filter out microscopic particles.
SILICOSIS WARNING
Grinding/cutting/drilling of masonry, concrete,-
metal and other materials with silica in their
composition may give off dust or mist contain-
ing crystalline silica.
Silica is a basic components of sand, quarts,
brick clay, granite and numerous other minerals
and rocks. Repeated and/or substantial inha-
lation of airborne crystalline silica can cause
serious or fatal respirator disease, including sil-
icosis. In addition, California and some author-
ities have listed repairable crystalline silica as a
substance known to cause cancer. When cutting
such materials, always follow the respiratory
precautions mentioned above.
RESPIRATORY HAZARDS
Grinding/cutting/drilling of masonry, concrete,metal and fumes containing
chemicals known to cause serious or fatal injury or illness, such as respirato-
ry disease, cancer, birth defects or other reproduction harm, if you are
unfamiliar with th risks associated with the particular process and/or materi-
al being cut or the composition of the tool being used, review the material
safety data sher and/or consult your employer, the material manufacturer/
supplier, governmental agencies such as OSHA and NIOSH and other
sources on hazardous materials. California and some other authorities, for
instance, have published lists of substances known to cause cancer, repro-
ductive toxicity or other harmful effects.
Control dust, mist and fumes at the source where possible. In this regard use good work practices and
follow the recommendations of the manufactures of suppliers, OSHA/NIOSH, and occupational and
trade associations. Water should be used for dust suppression when wet cutting is feasible. When the
hazards from inhalation of dust, mist and fumes cannot be eliminated, the operator and any bystand-
ers should always wear a respirator approved by NIOSH/MSHA for the materials being used.

GENERAL SAFETY
If the suction intensity drops, check that the
filters are not clogged or that hoses are not
kinked/clogged.
To properly store unit after use, hang the
vibrator with the head up and set the handle
(variable control assembly) in the open position
to permit the discharge of possible impurities,
contaminants and water.
The force exerted by an internal concrete vibra-
tor is controlled by the weight and the speed
at which the eccentric rotates. The centrifugal
force exerted can be arrived at by various com-
binations of weight (size of eccentric weight)
and the speed at which the weight rotates. For
years the most favorable working speed for a
vibrator was considered to be around 10,200
RPM (VPM) and consequently this figure is used
in many vibrator comparisons. More recently,
the optimum speed for compaction has been
accepted as being between 7500 and 9000
RPM.

Dust Collector Manual
GENERAL SAFETY
TOOL USE AND CARE
1. Only qualified persons should operate the
machine. Make sure you operate and service
your machine according to the instructions list-
ed in this manual.
2. When positioning the machine for drilling,
always face the drill. DO NOT operate with your
back to the machine. Facing the machine during
positioning allows the operator to have better
control of the machine.
3. DO NOT force the machine. Use the correct
machine for your application. The correct ma-
chine will do the job better and safer at the rate
for which it is designed.
4. DO NOT use the machine if the switch does
not turn it on or off. Any machine that cannot
be controlled with the switch is dangerous and
must be re-paired.
5. Disconnect the machine from the power source
before making any adjustments, changing ac
cessories or storing the machine. Such preven-
tative safety measures reduce the risk of start-
ing the machine accidentally.
6. Store machines out of reach of children and
other untrained persons. Machines are danger-
ous in the hands of untrained users.
7. Maintain machines with care and keep them
clean. Properly maintained ma-chines are less
likely to bind and are easier to control.
8. Check for misalignment or binding of moving
parts, breakage of parts and any other condi
tion that may affect the machines operation.
If damaged, have the machine serviced before
using. Many accidents are caused by poorly
maintained tools.
9. Use only accessories that are recommended
by the manufacturer for your model. Accesso-
ries that may be suitable for one machine may
become hazardous when used on another.
SERVICE
1. DO NOT run the drill unit while you make
adjustments and repairs unless the procedure
is approved.
2. Escaping fluid and air under pressure can have
sufficient force to penetrate skin causing seri
ous personal injury.
3. Before disconnecting lines, be sure to relieve
all pressure. Before applying pressure to the
system, be sure all connections are tight and
that lines, tubes and hoses are not damaged.
4. DO NOT use your hand to search for leaks. In-
stead, use a piece of card-board or wood.
5. Tool service must be performed only by quali
fied repair personnel. Service or maintenance
performed by unqualified personnel could
result ininjury or death.
6. When servicing a tool, use only identical
replace ment parts. Use of unauthorized parts
increase injury risk.

Dust Collector Manual
SET UP/ INSTILLATION
APPLICATION OF DUST COLLECTOR
1. If this dust collection system was purchased with
a new drill unit, it was installed at the factory. Skip
to section titled Adjustments. If this dust collection
system was purchased for a separate drill unit, con
tinue on to install.
2. Mount the main dust collector frame to your drill
unit. Four different mounting configurations are
typically used.
a. Minnich self propelled drill units manufac
tured after 2009 have mounting tabs welded
to the rear of the drill frame to accept the
dust collector.
b. Minnich models A-1CL, A-1C and A-2C
require a piece of angle iron with two mount
ing holes drilled in it
to be welded under the counterweight.
Refer to drawing labeled Dust Collection
System P/N A12200-1,2.
c. Minnich machine mounted models require
two brackets to be bolted to the drill frame
that have mounting holes for the dust collec
tor.
d. All other units use a universal mounting
adapter that will need to be welded to the
rear of the drill unit.
Care must be taken in choosing this location
so as to select one where the weight of the
dust collector will not cause damage to the
machine.
3. Refer to the appropriate plumbing diagram, ei-
ther manifold group or control group, for con-
necting the pneumatic control lines and main dust
collector supply line.
4. Remove the existing drill rod support guides and
install new dust collector guides in their place.
5. Route suction hoses from guides to collector. Be
sure to avoid any unnecessary bends or sharpturns
in the hose. Also, make sure that the hoses will not
be caught or kinked when raising or lowering the
drill bed.
ADJUSTMENTS
1. With the drill bed in the lowered drilling position,
slide the drill rod guides forward on the rail tube
so that the rubber section of the dust collector boot
just makes contact with the face of the slab. The
rubber can be trimmed as necessary if the guide
cannot be slide into the proper location. It may also
be necessary to trim the boots in order to accommo-
date keys or key ways on the face of the slab.
2. Make sure that the proper drill guide bushing has
been selected for the guide based on the hole diam-
eter to be drilled.Refer to your drill manual.
Dust Collector Set-Up/Installation Procedure
Set-Up/Installation

Dust Collector Manual 16
OPERATION/ MAINTENANCE
1.On most installations, the operation on the dust collector
is automatic. When the drill turns on, the appropriate
dust collection canister will automatically turn on and run
a timed reverse pulse cycle and turn back off when the drill
turns off. There is, however, a manual override switch that
will run the reverse pulse whenever the switch is activated.
This aids in the cleaning of the filters and should be done
whenever the filters are suspected of becoming clogged.
2. The dust collection bucks should be checked frequently
to make sure that they are emptied promptly when they
become full. If the buckets become over filled, the dust
will begin to accumulate around the filter cartridges,
which will cause damage to the collector. NOTE: The time
it takes to fill the buckets and the amount of dust collect
ed is dependent upon the diameter and depth of the
hole being drilled.
3. To empty buckets:
a. Make sure the dust collector is turned off.
b. Remove the lock pins from the pail re-
tainer.
c. Unlatch the catches to lower the bucket
and slide the bucket out from under the
dust collector.
d. Dispose the dust according to federal,
state,and local environmental regulations
and replace the bucket.
This procedure will result in employee expo-
sure to collected contaminant.
1. Make sure that the air supply is removed and trapped
air is exhausted before performing any service or Mainte
nance.
2. Check rod guide boot clearance to face of slab and ad
just to keep boots tight, replace as necessary.
3. Examine all suction hoses for wear or leaks. Also, make
sure dust particles do not clog hoses, especially at bends
or the base of inclines.
4. Periodically check filters to see that they are not clogged
or the filter media has not become torn.
5. To ensure optimum collector performance, always use
Minnich replacement parts.
Dust Collector Maintenance
Dust Collector Operation Procedure
Service
∆ Improper operation of a dust control system may
contribute to conditions in the work area or facility that
could result in severe personal injury and product or
property damage.
∆ Special care must be exercised in the operation and
use of all dust collection equipment where combustible
∆ DO NOT run the dust collector while you make
adjustments and repairs unless the procedure is
approved.
∆ Escaping fluid and air under pressure can have
sufficient force to penetrate the skin causing serious
personal injury. If injured by escaping fluid or air, see
a doctor at once. Serious infection or reaction can
develop if proper medical treatment is not adminis-
tered immediately.
∆ Before disconnecting lines, be sure to relieve all
pressure. Before applying pressure to the system,
be sure all connections are tight and that lines,
tubes and hoses are not damaged.
∆ DO NOT use your hand to search for leaks. Use a
piece of cardboard or wood to search for suspected
leaks.
∆ Tool service must be performed only by qualified
repair personnel.
∆ Service or maintenance performed by unqualified
personnel could result in a risk of injury.
∆ When servicing a tool, use only identical replace-
ment parts. Use of unauthorized parts or failure to
follow maintenance instructions may create a risk of
injury.
∆ Care should be taken when manually or hand clean-
ing the filter pack to prevent the tearing or punctur-
ing of the filter media.
∆ If collected material sticks to the filter packs, it may
require manual and hand cleaning.
∆ Manual or hand cleaning of the filter pack or col-
lector buckets will result in employee exposure to
collected contaminant.
∆ Proper employee procedures should be exercised
during this and other maintenance of the collector.
∆ For environmental compliance, it is highly recom-
mended to consult federal, state, and local environ-
mental protection agencies to determine proper
disposal of filters and collected materials.
and/or explosive materials are present. These mate-
rials may present a fire and/or explosive hazard.
∆ Minnich equipment does NOT contain fire or explo-
sive prevention equipment. A prudent user of dust
control equipment will consult with an expert in
explosion and fire control equipment, familiar with
their hazard and local codes for recommendations
on fire/explosion control equipment.
∆ Under no circumstances should anyone, including
the operator, allow any burning objects or lit cig-
arettes to enter the hood or ducting of any dust
control system
